裸眼水平井技术能够更大限度的有效开采油气层,为低渗油气藏的增产开发提供了保障,致密油气的高效开发离不开水平井分段压裂技术。水平井压裂措施增产技术已经大规模实现多级分段压裂,该技术已经成为低渗透油气藏提高采收率和提升开发综合效益的重要手段。然而,随着裸眼水平井技术的广泛应用,施工中出现管柱渗漏、断裂等问题逐渐增多。针对裸眼水平井分段压裂过程中出现的管柱漏失等问题,应用了连续油管穿电缆底带测试工具技术,通过井温法、流量法测试以及对照伽马曲线成功定位了漏点所在位置及漏失情况,为该井下一步的施工措施提供了重要的依据。
The naked-hole horizontal well technology can more effectively exploit the oil-gas layer, providing protection for the increase of the production of the low-permeability oil-gas reservoir. The efficient development of the tight oil and gas can not be separated from the horizontal well-section fracturing technology. Horizontal well fracturing stimulation technology has been large-scale multistage fracturing, the technology has become low permeability reservoirs to enhance oil recovery and enhance the overall efficiency of development an important means. However, with the widespread use of openhole horizontal well technology, there is a growing problem of column leakage and fracture during construction. Aiming at the problems such as column leakage during horizontal fracturing of open-hole horizontal wells, a coiled tubing through-cable test tool technology was applied. Through the well temperature method, the flow test and the control gamma curve, the location of the leak point was successfully located And the loss of the situation, the underground construction measures provide an important basis.
