The brine content of crude oils produced in Zhyangxi Oil Field, Shengli, has increased up to 60-70% and the scale inhibitor used in oil-gathering stations, HEDP, has lost its most functions. A scale inhibitor,BZF-2, composed of a phosphinic compound and a polyoxyethylene as main components is developed instead. The inhibition rates for deposition of inorganic salts, CaCO3 mainly, in various circumstances, corrosivity and compatibility of this scale inhibitior are studied in laboratory....

The brine content of crude oils produced in Zhyangxi Oil Field, Shengli, has increased up to 60-70% and the scale inhibitor used in oil-gathering stations, HEDP, has lost its most functions. A scale inhibitor,BZF-2, composed of a phosphinic compound and a polyoxyethylene as main components is developed instead. The inhibition rates for deposition of inorganic salts, CaCO3 mainly, in various circumstances, corrosivity and compatibility of this scale inhibitior are studied in laboratory. In field test performed in oil-gathering station Zhyang-52 over 4 months a rate of inhibiting Ca and Mg salts deposition≥98. 0% is observed and corrosion troubles are notably lessened with BZF-2 added in amount 10. 3mg/l.

A kind of phosphonic for inhibiting scale in formation was developed. The scale inhibitor contains the phosphonic group in structure of molecule. Optimum conditions for preparing phosphonic were obtained by using the orthogonal test method. Optimum phosphonic can be used for inhibiting scales of calcium carbonate, calcium sulfate and calcium silicate. The efficiency of scale-control is about 100% for calcium carbonate and calcium sulfate, and more than 90% for calcium silicate. The extent of corrosion and damage for formation of this scale inhibitor is lower than that of simulated inject water. This scale inhibitor can be used in the formation by using adsorbing method. .
