The Occidental Petroleum Corporation is offering $754 million in stock for the Zapata Corporation, a major oil services company, Zapata disclosed in Houston yesterday. Wall Street sources close to both companies said they had heard that Zapata told Occidental it was ''not for sale.'' Others close to the situation, however, insisted that such talk was just part of the bargaining process. Asked if the proposal was friendly, Armand Hammer, chairman of Occidental, said in a telephone interview: ''Yes, absolutely. I would not be a party to an unfriendly merger with anybody.''

An article last Sunday in Connecticut Weekly incorrectly reported the date for a celebration marking the 50th anniversary of Tweed-New Haven Airport. The event will be this Sunday.

Congress, which left town exhausted after a long, hard-fought dispute over Federal spending and tax policies, will return from its summer recess tomorrow to face a cluster of difficult issues and a new confrontation with President Reagan. After a White House meeting today with his top economic advisers, Mr. Reagan authorized an Administration move to trim an additional $10 billion to $15 billion from the budget for the next fiscal year as a way of holding the deficit to $42.5 billion. To achieve the new cuts, the President is expected to propose a legislative innovation as sweeping as his budget and tax plans: an omnibus appropriation bill, which would afford a yes-or-ng vote on an entire package of cuts rather than a piecemeal approach in which legislators would be subject to constituent pressures. 'The Next Battlefront' ''The appropriations front is the next battlefront,'' said Edwin L. Dale Jr., a spokesman for the Office of Management and Budget. Although economic problems are expected to dominate the fall session, the lawmakers will also turn their attention to other issues.

The Solidarity union asked today that the Government hold a national referendum on workers' rights in running factories. It also voiced support for other East European workers who might seek to set up their own independent unions. A motion, approved with only one dissenting vote at the union's national convention here, said that, if Parliament did not sponsor a referendum on self-management, then the union would do so itself. The 890 delegates also approved a message to workers in other Soviet-bloc countries who might try to establish unions free of party control.
