Coulomb Criterion

Formation mechanism of high-angle reverse faults has always been one of the questions concerning structural geologists. The mechanics of high-angle reverse faults does not conform to the Mohr-Coulomb criterion or Anderson’s theory of faulting. Geologists tried to explain the formation mechanism of high-angle reverse faults by inversion structure theory, Maximum Effective Moment Criterion and fault-valve model and so on. It is hard to explain the mechanism of high-angle reverse faults in Sanan oilfield with these viewpoints. It is considered that the cause of formation of such high-angle reverse faults was that the dip direction of normal fault plane has been overturned by the intensive superposed folding and interlayer gliding. “Overturned fault dip” can be regarded as a new type of inversion structure and supplements the existing types of inversion structure.

Western Turkey is one of the most spectacular regions of widespread active continental extension in the world. The most prominent structures of this region are E–W-trending grabens (e.g. Gediz and Büyük Menderes grabens) and intervening horsts, exposing the Menderes Massif. This paper documents the result of a recent field campaign (field geological mapping and structural analysis) along the southern margin of the modern Gediz Graben of Pliocene (∼ 5 Ma) age. This work provides field evidence that the presently low-angle ductile-brittle detachment fault is cut and displaced by the high-angle graben-bounding normal faults with total displacement exceeding 2.0 km. The evolution of the N–S extension along the Gediz Graben occurred during two episodes, each characterized by a distinct structural styles: (1) rapid exhumation of Menderes Massif in the footwall of low-angle normal fault (core-complex mode) during the Miocene; (2) late stretching of crust producing E–W grabens along high-angle normal faults (rift mode) during Pliocene–Quaternary times, separated by a short-time gap. The later phase is characterized by the deposition of now nearly horizontal sediments of Pliocene age in the hanging walls of the high-angle normal faults and present-day graben floor sediments. The evolution of extension is at variance with orogenic collapse and/or back-arc extension followed by the combined effect of tectonic escape and subduction rollback processes along the Aegean-Cyprean subduction zone. Consequently, it is misleading to describe the Miocene sediments exhumed on shoulders of the Gediz Graben as simple graben fill.

As a new type of heating equipment, the heat medium heater furnace overcomes the shortage of the traditional heating methods such as the boiler, heating furnace. Through the comparison and analysis of the field application between the heat medium heater, YQWP - 4000/1.6/220/180-QT, and steam boiler in a central gathering station of Changqing oil field, results indicated: in the condition of 0.3 MPa pressure and 200 °Ctemperature above, the heat medium heater is higher thermal efficiency, more safety and security than steam boiler, and it do not pollute the environment and significantly save energy. One the heat medium heater saves by 982700 RMB than one set of steam boiler per each year. Due to the good economy, heat medium heater is suitable for the heating and heat supply of the large-scale central gathering station in the oil field. Thus, heat medium heater has a good application prospects. And the field application of the heat medium heater provides oil field energy saving and safe production with a certain reference in oil field.

The Cost

At present, the pump setting depth of machine wells in Tahe Oilfield is universally too deep as the reservoir is buried deep, viscosity of heavy oil is high, and the producing energy weakened. This will increase the input of sucker rod, oil tube material and lead to enlarge suspension point load of pumping unit mule head and energy consumption. According to the problems, on the basis of the regularity of distribution of wellbore pressure field, viscosity field, temperature field, this paper puts forward a new matching lifting technology: moving down the point of blending and picking up the pump setting depth. Moving down the point of blending can reduce the producing energy loss and enforce the crude oil’s fluidity in the wellbore ,and picking up the pump depth can reduce the cost and energy consumption, Field test shows that after the new type matching lifting technology implement, test wells are normal in operation. The pump setting depth is partly picked up and pumping unit load decreases. The single well saves thin oil by more than 10%.

Geologic Environment

The Teton normal fault crops out along the eastern base of the Teton Range and relative motion across this fault has both uplifted the Teton Range and down-dropped Jackson Hole. On surface maps the normal fault appears to lie across older Laramide faults at a high angle, thus suggesting that previous structures had little to do with the position of the normal fault. Therefore, this field study was undertaken to test the following question: have preexisting Laramide or basement structures affected the position and/or geometry of the Teton normal fault? This question becomes important when considering the potential for contemporary earthquakes along the Teton normal fault and understanding the geologic environment of these earthquakes.

Average Corrosion Rate

Every year, water well inspection operations accounted for 27.3% of the total water well operations due to corrosion and scaling of downhole injection tools in the Dagang Southern Oil Field, which seriously affects the validity period of the injection string and the effect of the injection, greatly increasing the production cost. Therefore, through the research and experiment of anti-corrosion and anti-scaling technologies such as 00Cr25Ni7Mo3N dual-phase steel material, TiN coating, Ni-W-P coating and Ni-W-P-nSiO2 composite coating, a new type of anti-corrosion and anti-scaling technology for downhole injectiong tools has been developed. The field test results show that under the premise of ensuring the mechanical performance of the tools, the average corrosion rate of the supporting tools using the new anti-corrosion and anti-scaling technology is 0.0048mm/a, which is far lower than the industry standard 0.076mm/a. The successful test of this technology is of great significance to increase the effective period of the southern oilfield split injection and reduce production costs.
