Research on optimization of single well testing workload and efficiency

With the enlargement of production scale and the increase of survey and adjustment work, the mismatch between test requirement and test capability becomes more and more serious. In order to further control the test cost and improve the efficiency of survey and adjustment, according to the characteristics of the peripheral oil reservoirs and sections, differential management of survey and adjustment cycle and effective methods of matching injection points are actively carried out, on the basis of satisfying the development requirements and smooth operation of various indexes, solve the mismatch between test requirements and test capabilities. By analyzing the use cycle of test data under different conditions, the type of wells with extended use cycle is determined, which can effectively reduce the need of test work under the condition that the separate layer water injection is qualified. The distribution rules of different sizes of nozzles are statistically analyzed, and the selection rules of nozzles in special layers are made clear in advance to improve the debugging efficiency of injection allocation point.

The adjustment work canal on the Amudarya in the areas of the damless water intake

The paper presents the results of field research in the area of the damless water intake of the KMC on the Amudarya River. The article developed the optimal route and boundaries of the pioneer digging location, depending on the area of the main stream of the river relative to the point of the damless intake. It also provides hydraulic calculations for improving the condition of a damless water intake and recommendations for the rational use and placement of a dredgers fleet when laying a route of a ditch and cleaning it.

IMPROVING THE ACCURACY OF REGULATING THE CAPACITY OF PUMPING SECTIONS OF THE DISTRIBUTIVE TYPE FUEL PUMP

Due to the design features of ND-22 type of distribution pumps, equalization of cycle feed values between high-pressure sections is a rather complicated and time-consuming task, the solution of which is accompanied by repeated changes in the dimensions of the drive links with subsequent multiple metering of feed rates. In order to reduce the labor-intensiveness of adjustment operations and increase the accuracy of their performance, a technique and a device have been proposed, that significantly reduce the laboriousness of adjustment operations to equalize performance values between high-pressure sections, while simultaneously increasing the accuracy of their performance. The regularity of the change in the feed rate of the first section of the pump, the change in the length of the adjusting thrust of the metering drive is revealed. The linearity of the correlation relationship between the length of the adjusting thrust and the performance of the first high pressure section has been established. An equation, describing this relationship, is given. The graphic representation of the relationship between the change in the length of the adjustment thrust and the supply of the pump section allows it to be used as a nomogram for selecting the length of the thrust when a given feed cycle value is set during the adjustment work after repair.

ATTENTION CORRECTION POSSIBILITY IN PRIMARY SCHOOL DURING EDUCATING PROCESS IN SPECIAL SCHOOLS FOR PUPIL WITH INTELLECTUAL DISTURBANCES

Attention deviation for pupils with intellectual disabilities creates learning difficulties because pupils are not able to focus for long time, weakness and distraction of attention are typical, and it is difficult to switch from one activity to another. In order to reduce attention disorders, the authors offer the adjustment program and the working material „Development of Attention Features for Pupils with intellectual disabilities Mental Disabilities” for extra-curricular activities. The material was approbated in primary classes of special educational institutions for children with mental disabilities during the period from October 2014 to March 2015. The approbation results show that the program and the working material can be applied in attention disorders adjustment work with pupils with intellectual disabilities mental disabilities, because the levels of attention switching and division capacity, attention span and concentration have improved, despite the fact that the indicators still complied with the low attention switching and division capacities.
