This article mainly applies the injection-production balance board, combining the dynamic experience of oilfield development to optimize the adjustment method of injection and production parameters in fault area. Based on the law of material balance, considering the pressure limit of the fault plane and the dynamic data of development wells on both sides of the fault, by drawing the pressure balance chart of the injection and production system, the equilibrium formation pressure on both sides of the fault can be calculated. The adjustment direction is given based on the current injection and production status, so as to establish the injection and production parameter adjustment method in the study area.

Primary recovery is the stage of oil production by relying on the natural ability of the driving force of the reservoir. Kind of driving force that is water drive reservoir, depletion drive, segregation drive and a combination drive. The pressure drop occurred along its produced oil from the reservoir. Reservoir so that the driving force is the main parameter in maintaining reservoir pressure balance. Through the concept of material balance is the determination of the type of propulsion quifer reservoir and the power that generates driving force parameter analysis capability and aquifer in oil producing naturally. Then do the forecasting production to limit the ability of primary recovery production phase. Combination drive depletion of water drive and the drive is a driving force in the dominant reservoir Falipu Fields with a strongly water aquifer types of drives obtained through material balance equation. Calculations using the method of water influx Havlena & Odeh used as a correction factor for determining the type of propulsion reservoir and aquifer strength. Forecasting production in the Field Falipu generate recovery factor of 41% with a pressure boundary in 2050.

Sire Selection

The genetics of fitness traits, viz. replacement rate (RR) and selective value (SV) were studied in the flock of Malpura Sheep along the production parameters of the animals. The study was carried out on 10 years records for 2307 lambing sired by 187 sires. Sire wise incidence of replacement traits was as follows: abnormal birth (0.30%), sex ratio (49.98%), mortality (17.26%), culling (15.37%), RR on total lamb basis (33.98%) and RR on female lamb basis (68.44%). The selective value or adaptive value for the flock was 1.37. Sire did not affect abnormal birth, mortality, culling and SV significantly, whereas sire significantly affected sex ratio, and RR on total female lambs born basis. Ranking of the sires for selective value was incoherent with the ranking for production parameters such as age at first service, age at first lambing, weight at first service, productive flock life and longevity. Study indicated that the selection of sires for SV would not bring desired correlated change on any of the production parameter of the animals.

Based on the characteristics of low permeability, low pressure, poor effect of conventional waterflood development and low recovery efficiency in Chao Yanggou oilfield, advanced water injection is applied. Taking the Chang 10th block of Chao Yanggou oilfield as an example, the research on reasonable production time and pressure limit of advanced water injection in low permeability oilfield are carried out using methods of numerical simulation and reservoir engineering. The result shows that the average permeability of the Chang 10th block is 7.0×10-3μm2, the reasonable time of advanced water injection is about 6 months, and the recovery efficiency increases 2.26% compared with synchronized water injection. The successful application of advanced water injection development technology has some guidance on low-permeability oilfield development.

The Stability

The stability of combustion in the process of fire flooding requires not only a reasonable gas injection rate but also a matching exhaust rate. A reasonable injection-production balance system is very important. Based on the material balance of injection-production, the expression of injection-production ratio suitable for normal fire flooding production is established. The air injection rate of fire flooding combustion and oxygen consumption of formation pressurization is analyzed by this formula to calculate the gas production and liquid production in combustion. The reasonable injection and production parameters for the oilfield are calculated by using the oilfield parameters. It can be seen that the calculated value of injection-production ratio is consistent with the actual value, which shows that the injection-production ratio is reasonable and can guide the adjustment of production parameters in the oilfield.

Up to now, the common method of reservoir well group that is dynamic connectivity, it mainly includes tracer testing, stress testing, well testing, and numerical simulation. The implementation of these methods is more complex, expensive, high cost, and will affect the normal production of the oilfield. Because of the convenient injection and dynamic data it can get convenient. This paper presents a method that using dynamic reservoir development data inverse well group connectivity. CART algorithm analysis and extraction of potential knowledge from the oilfield development. It establish direct mapping of logging data and well group connectivity relationship. Experiments show that using dynamic data to study well group connectivity relationship can greatly reduce the cost and as a result has a higher accuracy.
