Abstract


Infill technology is one of the oil fields to enhance oil recovery methods , one of the oil fields at home and abroad to improve the development effectiveness of conventional measures . Shuanghe Oilfield VIII IX oil group poor reservoir properties , is now well pattern well spacing of 250-300 meters irregular five -spot pattern . However, due to the injection wells water injection start pressure , water is difficult , and wells energy supplement injected water effective is poor , resulting in faster production decline , the development of poor results . According to statistics , VIII IX oil group composite decline of 10% , the natural decline of 15% , the waterflood degree of control is only 86% , the final water flooding recovery is only about 37% . It is necessary to the oil group VIII IX infill adjustment and improve performance . In this paper , the problems for the the group VIII IX oil reservoir geological conditions and development , integrated use of reservoir engineering methods and fine reservoir numerical simulation technology analysis of the adaptability of the network of existing wells , infill demonstrated a reasonable Note production wells from the and infill wells deployment , economic and technological boundaries , provides a basis for the next step infill wells deployment . The understanding achieved mainly in the following aspects : ① VIII IX major reservoirs of oil group of non- conventional vertical wells encryption preferred WELLS bias oil - water boundary five-point square well pattern . ② VIII IX oil group horizontal wells and vertical wells encryption preferred horizontal section parallel horizontal oil wells in the oil-water boundary vertical well injection five -spot pattern . ( 2 ) based on the VIII IX oil group starting pressure gradient the oil sands body area , economic indicators parameter calculated VIII IX oil group reasonable injector spacing of 200 m . ( 4 ) From an economic point calculated to play a vertical well infill wells required for the effective thickness of the lower limit of 4 meters. Geological reserves required to play a horizontal well lower limit of 5.75 × 10 ~ 4t , the lower limit of the effective thickness of the boundary is 3 meters . Finally, based on previous research to deploy 3 sets of infill program , re-use fine reservoir numerical simulation technology optimized Shuanghe oilfield VIII the IX oil group infill program , the infill program production forecasts .
