Abstract
A ccording to the features o f the deeply bur ied reservo irs, h igh tem pera ture, low permeability and com plicated structures in Zhongyuan O ilfie ld, we conduct a ser ies o f the developm ents to the water-based fracture fluid, the c lean ing fracture fluid and the o i-l based fracture fluid in fracture flu ids, and develop the new prepads and the new fracture additives through research ing the stim u lation m echan ism. In this paper, w e a lso descr ibe the re-fractur ing, the h igh-ang le w e ll frac tur ing, the m ultiple fractur ing, the CO2 foam fracturing, the integrated fractur ing techno log ies in tract and the ir related m atch ing eng inee ring, wh ich are regarded as the effective deve loping techn iques and are w idely used in Zhongyuan o ilfie ld.
