Study on Comprehensive Measures of Long-Term Stable Dense Oil Reservoir

Abstract:

water injection development is an effective means of tight reservoir to maintain formation energy, and high formation pressure is the basis of reservoir maintain a long-term and stable, therefore, give enough water injection, so as to maintain high pressure is the key to maintain the long-term stability of the reservoir. Liu Maoyuan block Changqing Oilfield is a typical part of tight sandstone reservoir, water injection wells long is not up to the demand of injection, after fracturing, acidizing by invalid injection measures, is not conducive to long-term and stable block. Therefore, research on comprehensive countermeasures of long-term stability of dense oil reservoir. Through the research and development of new antihypertensive drag reduction agent for the overall pressure on block; select suitable for dense reservoir single well stimulation measures and local boosting measures, measures ineffective wells and local abnormal pressure injection is difficult to solve the problem of the cause, to maintain formation pressure. A good result has been obtained by field test, effectively solve the tight reservoir by high-pressure injection resulted in not long-term stability problems, and provides a new idea and reference for solving dense reservoir long-term stability problem.
