摘要:
儲層在低礦化度和低孔隙度情況下,飽和度測井應用效果差,孔隙度和泥質含量計算不夠準確導致剩余油誤判,針對這些問題引進四中子測井。四中子測井采用镅鈹中子源,通過4個探測器采集中子-中子、中子-伽馬雙物理過程的信息,減少對裸眼井信息的依賴; 利用活化鋁元素計算泥質含量; 在孔隙度計算和流體識別時,綜合雙物理過程的測量方式減小井眼環境及流體性質影響,放大流體響應信息; 較精確地評價套后地層物性特征及剩余油分布情況。多區塊、多井次的現場應用證明四中子測井在剩余油評價中使用效果良好
Abstract:
Cable control layered testing technique uses cables to control downhole switches, switches can be turned on or off at any time. All manometer data can be observed and recorded on the ground instrument. The technique uses tubing to put the packer, switch manometer instruments and tools into the target zone, and uses cables to connect the switches and manometers in each layer and eventually connects to the surface instruments. If the technology needs to cooperate with the oil extraction pipe pump, it needs to run the pipe string twice. If cooperating with the rod pump or screw pump into the string it only needs to run the pipe string once. The cable control layered testing technique can measure the pressure and temperature of each layer, obtain the seepage parameters calculate the yield of each layer, and provide suitable production pressure difference. Combined with the interference test, the connection between the well and the water injection well can be clarified to determine the minimum start-up water injection amount of the well. This study is putting forward the method of calculating flow with pressure and designing the pressure balance switch and the sand control tubing string. Compared with the storage stress test, the cable control layered test has the advantage of not being limited by battery life and data direct reading
