Abstract
The reservoir passes the peak of reserves.The reserves of new investment and development are decreasing year by year. The reserve resources are insufficient. Some of the main development units have entered the stage of secondary or tertiary oil recovery. The dependence of stable oil and gas production on measure production increases continuously. Under this background, the workload of oil well measures increases year by year. It is difficult to control the operation cost of measures. As a result, the overall economic benefits of oilfield enterprises have been declining year by year.The cost of ineffective measures has become an important factor restricting the economic development of oilfields. Through the construction of measures benefit evaluation system.Strengthen the controllability and predictability of each stage of implementation. Special attention should be paid to the pre control management of high cost wells and the transformation of production mode of low efficiency wells. Strictly follow the "ex ante argument, adjustment in matters, and post evaluation optimization" measures to run the management mode. Realize the reasonable allocation of workload and cost, and improve the effective rate of return of funds.
Highlights
The depth analysis of sand body distribution and physical property difference is carried out which provides data basis for the adjustment of development plan and 3D reservoir geological model
The annual measure structure adjustment.Monthly measure implementation structure and operation arrangement are all based on small layer and reservoir.Based on dynamic response and the principle of oil and water well coordinated treatment achieve scale effect
Starting from the calculation of recoverable reserves, the calculation model of increasing reserves and increasing production is established on the basis of the static elements system framework and correlation research of development units and production measures
Summary
3.1 build a three-level evaluation system of measures and benefits to realize the whole process control.
